Abstract
Abstract A gravitational settler vessel for use in combination with a mixer. The settler vessel is adapted for the separation of a liquid-liquid dispersion in which the dispersed phase amounts to 10 to 70 percent by volume of the total dispersion. It comprises a settling chamber, at least two stacks of sloping, vertically spaced plates, and at the two sides of each such stack there are vertical channels, one of which serves for conducting the ascending lighter phase to a light phase-collecting chamber and the other for conducting the descending heavier phase to the heavy phase-collecting chamber. The vertical channels may be formed either between two vicinal stacks or between a stack and a sidewall of the settling chamber.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
A gravitational settler for the separation of the two phases of dispersions of mutually immiscible liquids of different specific gravities where the dispersed phase amounts to 10 to 70 percent by volume of the total dispersion; which settler comprises an inlet header, a settling chamber, an upper light phase-collecting chamber and a lower heavy phase-collecting chamber; at least two stacks of sloping, vertically spaced plates located within the settling chamber and so disposed that on one side of each stack there exists a vertical collecting channel towards which the plates of the stack slope downwardly, and at the opposite side of the same stack there exists a vertical collecting channel towards which both plates of the stack slope upwardly; a vertical partition perforated at least in a region coextensive with a middle zone of the stacks, separating the inlet header from the settling chamber; and perforated, substantially horizontal partitions separating the bottom region of the settling chamber from the heavy phase-collecting chamber, and the top region of the settling chamber from the light phasecollecting chamber.
Claim 2
Dependent Claim
175 words
A gravitational settler for the separation of the two phases of dispersions of mutually immiscible liquids of different specific gravities where the dispersed phase amounts to 10 to 70 percent by volume of the total dispersion; which settler comprises an inlet header, a settling chamber, an upper light phase-collecting chamber and a lower heavy phase-collecting chamber; at least two stacks of sloping, vertically spaced plates located within the settling chamber and so disposed that on one side of each stack there exists a vertical collecting channel towards which the plates of the stack slope downwardly, and at the opposite side of the same stack there exists a vertical collecting channel towards which both plates of the stack slope upwardly; a vertical partition perforated at least in a region coextensive with a middle zone of the stacks, separating the inlet header from the settling chamber; and perforated, substantially horizontal partitions separating the bottom region of the settling chamber from the heavy phase-collecting chamber, and the top region of the settling chamber from the light phasecollecting chamber.
Claim 3
Dependent Claim
79 words
A settler according to claim 1, being a substantially cylindrical apparatus in which the header has circular cross section and occupies the center of the settler, the settling chamber is disposed concentrically round the header, the collecting chambers form a concentric jacket round the settling chamber, each of them occupying about half the height of the settler, and a plurality of stacks are disposed radially and have substantially circular sectorlike shape, with radial, substantially rectangular collecting channels between them.
Claim 4
Dependent Claim
47 words
A settler according to claim 1, being a substantially rectangular apparatus in which the stacks extend in either its longitudinal or its transverse direction, the header is located at one end of the stacks and the collecting chambers are located at the opposite end of the stacks.
Claim 5
Dependent Claim
24 words
A settler according to claim 1, wherein the angle of slope of the plates is from 2to 40* , preferably from 5* to 15*.
Claim 6
Dependent Claim
38 words
A settler according to claim 1, wherein the aggregate cross section of flow of the partition between the header and settling chamber is larger than that of the conduit through which the dispersion is fed to the header.
Claim 7
Dependent Claim
27 words
A settler according to claim 1, wherein the distance between the plates of the stacks is from 5 to 60 mm., preferably from 10 to 40 mm.
Claim 8
Dependent Claim
29 words
A settler according to claim 1, wherein the width of the plates amounts to 5 to 20 times the vertical distance between each two consecutive plates of each stack.
Claim 9
Dependent Claim
29 words
A settler according to claim 1, wherein the distance between each two consecutive plates of a staCk is about one-hundredth to one-tenth of the total height of that stack.
